@dean-long, good ideas, but they require some investigations and non-trivial changes.
Maybe it's better to integrate this simple approach, that can be useful for performance experiments and can possibly be backported to 17u/11u due to its simplicity, and then implement one of your ideas separately?
Since the suggested InlineCacheBufferSize option is experimental, it can be dropped later without any notice.
